Method Detail

exposeServiceDeploymentInfo

protected io.siddhi.core.stream.ServiceDeploymentInfo exposeServiceDeploymentInfo()

Specified by:

exposeServiceDeploymentInfo in class io.siddhi.core.stream.input.source.Source

init

public io.siddhi.core.util.snapshot.state.StateFactory init(io.siddhi.core.stream.input.source.SourceEventListener sourceEventListener,
                                                            io.siddhi.core.util.transport.OptionHolder optionHolder,
                                                            String[] requestedTransportPropertyNames,
                                                            io.siddhi.core.util.config.ConfigReader configReader,
                                                            io.siddhi.core.config.SiddhiAppContext siddhiAppContext)

The initialization method for Source, will be called before other methods. It used to validate all configurations and to get initial values.

Specified by:

init in class io.siddhi.core.stream.input.source.Source

Parameters:

sourceEventListener - After receiving events, the source should trigger onEvent() of this listener. Listener will then pass on the events to the appropriate mappers for processing .

optionHolder - Option holder containing static configuration related to the Source

configReader - ConfigReader is used to read the Source related system configuration.

siddhiAppContext - the context of the SiddhiApp used to get Siddhi

onResponse

public void onResponse(Event response,
                       Map<String,String> siddhiRequestEventData)

onResponse

public void onResponse(Object response,
                       Map<String,String> siddhiRequestEventData)

getOutputEventClasses

public Class[] getOutputEventClasses()

Returns the list of classes which this source can output.

Specified by:

getOutputEventClasses in class io.siddhi.core.stream.input.source.Source

Returns:

Array of classes that will be output by the source. Null or empty array if it can produce any type of class.
